摘要

海藻是一种经济商品,被广泛种植,有Eucheuma cottonii (Kappaphycus alvarezii)和Eucheuma spinosum。改进生产的努力是通过改进栽培方法以达到最大产量而发展起来的。种植距离是影响生产增长和增加的因素之一。该研究的目的是测试生长距离与K.阿尔瓦罗海藻生长速度的差异。使用的研究方法是定量方法与种植距离的治疗。所使用的实验设计是一个随机的设计,包含3种生长距离治疗(20厘米,30厘米,40厘米)和每个测试分别进行3次重复。所观察到的参数是每周的具体增长速度,绝对增长速度和生命周期K.阿尔瓦罗。研究结果表明,不同的种植距离影响绝对的生长速度和特定的生长速度,而且每次治疗都有明显的不同。统计分析表明,在每次测量过程中,每次治疗的生长速度都在增加。以平均体重545.9克的农产品为例,以平均每天384%的生长速度为例。Seaweed是印度尼西亚leading经济商品之一。在印度尼西亚,最严重的文化是Eucheuma cottonii (Kappaphycus alvarezii)和Eucheuma spinosum。加强生产的努力是通过对最大生产代表的文化修改而发展起来的。植物空间是影响营养吸收的主要因素之一,因为空间会影响水吸收营养的流动。这种对种植园大小的不同的研究使其在最好的生长速率上保持增长。研究用的方法是在纸上接受的量量方法。实验设计使用了3种spacing treatments(20厘米,30厘米,40厘米)和3种复制品,进行了完全的分级设计。观察者观察到的是罕见的增长速率,绝对的增长速率和K.阿尔瓦罗的生存速率。不同的plant spa递显示,这种不同的plant spa递有一种影响,这种影响在不断增长,而且在每个试验中都有显著的不同。统计分析的结果表明,在每一种手段的每一种手段中,增长都在增长。发明了最优、最优增长的时空后,人们在30厘米的空间中发现了545.9 g和平均增长率3.84%。

Perbedaan Pertumbuhan Rumput Laut Kappaphycus alvarezii Terhadap Jarak Tanam
Rumput laut merupakan salah satu komoditas ekonomi yang menjadi unggulan Indonesia dan jenis yang banyak dibudidayakan adalah jenis Eucheuma cottonii (Kappaphycus alvarezii) dan Eucheuma spinosum. Usaha peningkatan produksinya dikembangkan melalui modifikasi metode budidaya untuk mencapai hasil produksi yang maksimal. Jarak tanam merupakan salah satu faktor yang berpengaruh terhadap pertumbuhan dan peningkatan produksi. Penelitian ini bertujuan menguji perbedaan jarak tanam terhadap laju pertumbuhan rumput laut K. alvarezii. Metode penelitian yang digunakan adalah metode kuantitatif dengan perlakuan berupa jarak tanam. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan 3 perlakuan jarak tanam (20 cm, 30 cm, 40 cm) dan masing-masing perlakuan dengan tiga ulangan. Parameter yang diamati yaitu laju pertumbuhan spesifik mingguan, laju pertumbuhan mutlak dan kelulushidupan K. alvarezii. Hasil penelitian menunjukkan jarak tanam yang berbeda berpengaruh terhadap pertumbuhan mutlak dan laju pertumbuhan spesifik serta terdapat perbedaan yang nyata dari tiap perlakuan dari waktu ke waktu. Hasil analisa statistik menunjukkan peningkatan pertumbuhan pada masing-masing perlakuan dari setiap waktu pengukuran. Jarak tanam yang memberikan hasil pertumbuhan terbaik pada jarak tanam 30 cm dengan hasil berat rata-rata 545,9 gr dan rata-rata laju pertumbuhan spesifik 3,84% per hari.  Seaweed is one of Indonesia’s leading economic commodities. The species that are widely cultivated in Indonesian waters are Eucheuma cottonii (Kappaphycus alvarezii) and Eucheuma spinosum. Efforts to increase production are developed through modification of cultivation methods to achieve maximum production results. Plant spacing is one the factors that affect growth and increased production in relation to nutrient absorption because the spacing will affect the movement of water carryiing nutrients. This study aims to examine differences in plant spacing on the optimal growth rate of K. alvarezii seaweed for the growth of K. alvarezii. The research method used is a quantitative method with treatment in the form of spacing. The experimental design used was a completely randomized design using 3 spacing treatments (20 cm, 30 cm, 40 cm) and 3 replications. Parameters observed were weekly specific growth rate, absolute growth rate and survival rate of K. alvarezii. The results showed that different plant spacing had an effect on absolute growth and specific growth rate and there were significant differences in each treatment from time to time. The results of statistical analysis showed an increase in growth in each treatment from each measurement time. The spacing that gave the best and optimal growth results was found in the 30 cm spacing treatment by producing an average weight gain of 545,9 g and an average specific growth rate of 3,84% per day.

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
